THE COMPLETE DORMANT 
Since 1904, Scalecide has been famous for its effectiveness 
against the San Jose scale and all other scale insects, because 
it has always been a miscible oil of the highest quality. But 
Scalecide is not only a scale spray; it kills all other pests which 
winter on the tree. It is the complete dormant spray. Applied 
as a delayed dormant spray in the spring, diluted 1 to 15 
(12 gallons to a 200-gallon spray tank), Scalecide controls 
aphis, European red mite, pear thrips, and red bug; diluted 
1 to 12% (15 gallons to a 200-gallon spray tank), it also con- 
trols leaf-roller. Applied in the fall (1 to 15), Scalecide con- 
trols peach leaf-curl and pear psylla. Either fall or spring 
spraying with Scalecide (1 to 15) controls scale, bud-moth, 
case-bearer, leaf-miner and fungous cankers. 
Scalecide Is Guaranteed 
Scalecide is guaranteed to make a better orchard than lime- 
sulphur or oil-emulsion. Ask for copy of full guarantee. Scalecide 
costs more but it is worth it because it does so much more than 
any spray you can use. The year-after-year use of Scalecide shows 
a marked invigorating effect on the trees. 

Deposit on drum refunded when returned to B. G. Pratt Co., Hackensack, N. J., prepaid.

SPRAY 
Spray Ornamentals with Scalecide 
Spray any tree or vine which drops its foliage in winter 
with Scalecide, just before the buds start in the spring. Spray 
lilacs, rose bushes, and other shrubs. Use Scalecide, 1 to 15, 
on maples, dogwoods, elms, and other shade trees. This spray 
is for San Jose scale, oyster-shell scale, scurfy scale, tulip 
scale, red mite, woolly aphis, green aphis, etc., as well as 
building up the general vigor and vitality of the trees. 
For conifers, spruces, pines, etc., spray with Scalecide, 1 to 
20, just before the new growth starts in the spring. 
For evergreens, euonymus, etc., spray at the same time 
with a dilution of 1 to 25. 
Para-Scalecide Method 
Scalecide can be obtained containing paradichlorobenzene for 
the control of borers in peach and other trees (see page 64), or you 
can make your own by dissolving 2 pounds of paradichlorobenzene 
in 1 gallon of Scalecide. This is diluted 1 to 7 and sprayed or 
poured about the base of the trees in the fall.
